SELFADJOINTNESS OF INTEGRAL AND MATRIX OPERATORS

open access: yesJournal of the London Mathematical Society, 2006
Criteria for selfadjointness of integral operators, including matrix operators, based on our earlier domination results are established. The range of applicability is elucidated by carefully chosen examples, not covered by previously known criteria.

Stable numerical solutions of fractional partial differential equations using Legendre scaling functions operational matrix

open access: yes, 2018
In this paper we solve initial and boundary value problem for non-homogeneous fractional order partial differential equations. Here we use operational matrix approach to construct approximate solutions using Legendre scaling functions as basis.

A numerical scheme for constrained optimal control problems [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2019
In this paper, a numerical technique is proposed to solve optimal control problems (OPCs) of Volterra integral equations (VIEs). We apply the linear B-spline polynomials to solve OPCs by VIEs. The B-spline function divides the interval into sub-intervals

A Polymorphic Register File for matrix operations [PDF]

open access: yes2010 International Conference on Embedded Computer Systems: Architectures, Modeling and Simulation, 2010
Previous vector architectures divided the available register file space in a fixed number of registers of equal sizes and shapes. We propose a register file organization which allows dynamic creation of a variable number of multidimensional registers of arbitrary sizes referred to as a Polymorphic Register File.

Haar Wavelet Based Implementation Method of the Non–integer Order Differentiation and its Application to Signal Enhancement

open access: yesMeasurement Science Review, 2015
Non–integer order differentiation is changing application of traditional differentiation because it can achieve a continuous interpolation of the integer order differentiation. However, implementation of the non–integer order differentiation is much more
